I went to flush and put antifreeze into my 2008 mercruiser mag 350 engine. It has 2 blue drain plugs on either fron side of the engine and 1 blue drain plug top middle by thermostat. Anyway, we flushed and drained fine, but afterwards a noticed a drip coming from the portside drain plug, I went to tighten it and the drip because more frequent. I swapped the drain plug with the top middle plug, and still the same results. I then put some teflon tape on the drain plug and reinserted, same result. I took a video with my Iphone -hope I can post it, and it shows the drip coming from right behind the plug. Can anyone comment on what this might be? The parts manual seem to say its my water distribution housing, but I can not get a clear picture of it from underneath. And I do not remember it dripping before. I am having trouble with youtube, will upload shortly.
SO, if you've seen this before, should I epoxy or replace. The part looks to be 150$ and if they don't have to remove the engine, Im thinking 200$ to install?
